What is a TPM?

TPM is a security technology that increases the system security against software vulnerabilities.

Practically, the TPM is used for multiple features that increase the security of your device:

  • BitLocker Drive Encryption: Automatically encrypts the system drive to keep your data safe.
  • Data Execution Prevention: Prevents unauthorized applications like malware from executing in memory.
  • Windows Hello: Secure user authentication without password.
  • Secure Boot and Measured Boot: Block malicious drivers and rootkits from intercepting the boot process of the Operating system.

What is the difference between TPM 1.2 and TPM 2.0?

  • Version 2.0 provides higher security standards and better reliability.

Are Intel PTT and AMD fTPM the same as TPM?

PTT or Platform Trust Technology is a firmware extension from Intel that supports Microsoft TPM requirements.

fTPM or Firmware TPM is a firmware technology from AMD that supports Microsoft TPM requirements.

Microsoft Windows works with both, PTT and fTPM among other TPM implementations.
